IMPROVEMENT IN THlLL-COUPLINGS.

Specification forming part of Letters Patent No. 14.2,274, dated August26, 1873; application filed May 6, 1873.

To all 'whom it may concern Be it known that I, BARNET It. RAPP, ofWestchester, Chester county, Pennsylvania, have invented an Improvementin Thill-Oouplin gs, of which the followingis a specification:

The object of my invention is to improve the thill-coupling, for whichLetters Patent No. 124,159 were granted to myself and Wm. H. Lawson,assignee, on the 27th day of February, 1872 and my improvement consistsin dispensing with the long arm of the cam-lever D, described in thesaid patent, and substituting therefor a socket, e, for the reception ofthe end of a lever, E, as shown in the side view, Fig. 1, of theaccompanying drawing.

A represents the carriage-axle; B, a clip passing around the same; 0, anextensionplate secured to the clip D, the cam-lever jointed to the outerend of the extension-plate by a pin, a, and arranged, when turned up, asshown in the drawing, to bear against an elbowplate, F, and thuscompress ablock of rubber, G, between the said elbow-plate and the thillH, Which is jointed to ears (1 on the clip by a pin retained in place byarms f on the camlever, all as described in the said patent, in which,however, the cam-lever was provided with, and operated by, a longpermanent arm, the latter being more or less unsightly and in the way.In place of this permanent arm on the cam-lever, I form on the latter asocket, e, for the reception of the end at of a lever, E, the

said end as being toothed or serrated so that it can retain its hold inthe socket. By depressing this lever E the cam-lever may be turned tothe position shown by dotted lines, thereby relieving the thill from thepressure of the rubber-block G, and at the same time uncovering the endsof the pin which connects the thill to the ears (I d, and permitting thesaid pin to be withdrawn. By the same lever E the cam-lever may bereadily restored to its original position when the shafts of the vehiclehave been readjusted t0 the coupling, after which the end of the lever Emay be withdrawn from the socket e of the cam-lever and deposited in asuitable place ready for use. I prefer to make the lever E with atransverse handle, y, at its outer end, so that this handle may be usedas a hammer-head to drive out the pin which connects the thill to theears d,

should there be any difficulty in removing said I claim as my invention-The clip D, having a socket, e, for the reception of the end of adetachable lever, E, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
